PATENT OFFICE OF SHERBROOKE, QUEBEC, CANADA, ASSIGNOR OF ONE-HALF TONAPOLEON J'UTRAS, OF SHERBROOKE, CANADA 7 LAMP Application filed August2, 1928. Serial No. 297,076.

The present invention relates to improvements in lamps and hasparticular reference to a lamp known as a votive lamp.

Heretofore, the. lamps, known as votive lamps, employed in churchservice, have been usually constructed of glass. These lamps have beenfound defective in that they are naturally quite brittle and arefrequently cracked by. the heat of the lighting flame.

An important object of the invention is the provision of alamp casingconstructed to resist the heat of the lighting flame.

,A further object of the invention is the provision of a lamp of theabove character which will be comparatively durable.

Other objects and advantages of the invention will become apparent asthe description progresses. In the accompanying drawing forming a partof this specification and in which like reference characters areemployed to designate corresponding parts throughout the same:

Figure 1 is a perspective view of the lamp constructed in accordancewith the present invention,

Figure 2 is a side elevational view partly in section, and

Figure 3 is a transverse section taken on the line 33 of Figure 2.,Referring to the drawing, wherein for the 1 purpose of illustration isshown a preferred embodiment of the invention, the numeral 5 generallydesignates the lamp casing frame,

, bodies a flat, preferably circular bottom plate 6. Formed integralwith or connected to the bottom plate 6 and extending vertically fromthe diametrically opposed sides thereof, are longitudinal side ribs 7supporting on their upper ends a top ring 8. The upper annular 7 ring 8is preferably larger in diameter than the bottom plate so that the sideribs 7 are arranged in upwardly diverging positions.

The frame 5 is adapted to form a durable support for an intermediatewaist section 9 which is formed of substantially transparent, heatresisting material, preferably comprising mica sheets of colorless orcolored struc-' ture. The waist section 9 is formed in preferablyconstructedof metal, which emfrusto-conical arrangement, the upper andlower annular edges being embedded in grooves formed in the upper ring 8and bottom plate 6, respectively, while the intermediate portion thereofextends through longitudinal slots formed in the ribs 7 to securelybrace the side walls of the waist section.

The lamp casing described in the foregoing, is then filled with wax 10,or any suitable substance,in which is embedded a wick. The wick isignited and burns in the casing until the wax or other filler isconsumed. It will be apparent, from the foregoing description, that thepresent lamp casing will provide an efficient and durable casingstructure designed to resist the heat of the flame and preventaccidental breakage thereof.

It is to be understood that the form of my invention herein shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes as to the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claim.

Having thus described my invention, I claim A votive lamp casingcomprising the combination of a cast frame including an annular baseplate, a plurality of diametrically opposed ribs extending verticallyfrom the base plate, an annular ring secured on the upper ends of theribs in a plane parallel with the base plate and having a diameter ofincreased dimension with respect to the base plate, with 'a sheet ofmica arranged in frusto-conical formation between the base plate and thetop ring and secured in the ribs at the time of casting the frame.

In witness whereof I have hereunto set my hand.

FRANK MERCIER.
